When high power is needed, the capacitor cathode would play the main role of peak power output; when high energy is demanded, the air catalytic cathode would display its high energy character. The adjustability of power output and energy output demonstrate that the proposed lithium–air capacitor–battery should be a promising power system for future electric vehicles.

Had something come across my Facebook page that's making wild claims. Maxergy by 27th Century Technologies, Inc. Perpetual self charging batteries. Hopefully Tesla has R&D people who hunt these claims down and see if any potential is there for future battery replacements.
